Question

How many distinct triangles can be formed for which m∠E = 64°, g = 9, and e = 10? triangle(s)

Answer 1

Using the law of sines, it is found that 1 triangle can be formed with the given conditions.

What is the law of sines?

Suppose we have a triangle in which:

• The length of the side opposite to angle A is a.

• The length of the side opposite to angle B is b.

• The length of the side opposite to angle C is c.

The lengths and the sine of the angles are related as follows:

$\frac{\sin{A}}{a} = \frac{\sin{B}}{b} = \frac{\sin{C}}{c}$

Hence, for this problem, we have that the relation is:

$\frac{\sin{64^\circ}}{10} = \frac{\sin{G}}{9}$

$\sin{G} = 0.9\sin{64^\circ}$

$\sin{G} = 0.8089$

$G = \arcsin{0.8089}$

G = 54º

A triangle can have one angle of 64º and another of 54º, hence 1 triangle can be formed with the given conditions.
